Isn't the cost of those services also a function of the number of requests? E.g. they bill on a request basis, not an hourly cpu time basis?

This pretty common in the financial trading space. It's usually referred to as kernel bypass. It's how HFT's are able to achieve < 100 microsecond tick to trade response times.

The presence of FIX in their offering indicates the company was built by or is run by someone who has some (possibly dated) understanding of what is going on when it comes to implementing trading systems.

https://www.bitfinex.com/ allegedly (or at one point) claims to offer FIX connectivity. And they have swaps for BTC.

When the fares do not support car upkeep + owners time value they will stop getting lower. Assuming all uber drivers are behaving rationally (not a dig at uber, just that people do irrational stuff all the time).

But how will these leading-edge metrics enable us to deliver paradigm shifting solutions to our customers while simultaneously reducing costs and increasing operational efficiency?

Can your CPU affinity wrappers be used with plain old java threads? Or does it only work with your realtime threads? I briefly inspected Affinity.java and it looks like it just takes the OS's thread ID so this may be fairly straightfor

We have special hardware that syncs our servers to an atomic clock in Colorado. It's about +/- microseconds off. Not sure about sub microsecond tho. Another problem with this is you will run into clock drift and NTP time adjustmen

I think you are right to be fearful. Trust isn't good enough. As our machines become more complicated, formal methods of verification & validation will become necessary for the daily programmer. We cannot trust that it is correct,

Thanks for sharing this. Curious where you get your java framework/cool api news from? I hadn't heard about this.

It's surprising that they didn't destroy the entire computer to cover up what they were hiding. This seems like a relatively small subset of components to investigate.

I live about a 5 minute walk from Castro St. in Mountain View. I always walk down there whenever I go to eat food because I enjoy walking. My roommate cannot comprehend why I do this instead of driving. I think it has to do with the fact th

Continuing with the example, lets say I'm trying to hit my price, and only 300 shares are available on BATS and another 700 are available on some other venue. Would BATS send an order for the remaining 700 to the other venue, or does i

I work in FX, so I'm unfamiliar with the exact workflow. Say I submit a buy order for 1k shares of AAPL to BATS. What exactly happens?

As I understand it, George W. Bush deregulated the stock market and allowed multiple venues to compose the market. This resulted in stock trading becoming distributed among multiple venues. When a retail customer submits an order to an exch

He identified problems and proposed a solution to those problems. You've identified problems and used them as an excuse to continue the status quo or bring us back to a previous and less safe time in history. What exactly do you find o

I thought of this as well, but more along the lines of protein folding. I think finding a cure for one of those diseases would be more than enough for most people to justify the power consumption.

The lower 20% (Didn't it recently go up to 29%?) rate is only applicable if you have held the asset for 2 years. If you buy and sell short term, as I have, then short-term capital gains applies.

I would also add that a lot of venue arbitrage strategies are too cumbersome to implement in bitcoin because you need to store collateral with multiple exchanges unlike equities or other proper financial markets.

Gox's prices are off market because the market @ Mt. Gox is pricing in the fact that you can't cash out on that exchange. This happened to CampBX as well once they stopped ACH/WIRE withdraws. They were usually near bitstamp&#

Another thing that tends to confuse people about bitcoin as well is that there are 100,000,000 satoshis per bitcoin. This hasn't really been communicated by the press. Every person who doesn't follow bitcoin closely or understand

Could you please elaborate on your fantasy trades remark? I was aware of Mt. Gox fiat issues, and now the BTC hold. Were they accused of booking fictitious trades?

He's still the chairman of the Microsoft board. I read bloomberg for most of my business news and lots of op-ed contributors there stipulate that this is making it harder for Microsoft to find a replacement CEO.

My math is wrong for total number of units of currency. It should be 2.1 * 10^15, which is 2.1 quadrillion. At the height of the financial crisis the notional value of all Credit Default Swaps was ~640 trillion.
